SAN ANTONIO — Emergency responders were searching Braunig Lake Sunday afternoon for a man who disappeared after his boat capsized.

The man and a woman started having boat troubles just before 4 p.m. Sunday when they were about a quarter-mile away from shore, fire officials said. As they tried to return to shore, the boat capsized.

A kayaker pulled the woman out of the water, but the man could not be found.

It was not immediately clear if the man knew how to swim or if he was wearing a lifejacket.

Fire officials and game wardens were searching the lake in rescue boats. The San Antonio Police Department's helicopter was searching from the sky.

If they did not find the man before sundown, crews were expected to resume the search in the morning.

One week ago, a 9-year-old boy, Emmanuel Rojas, drowned in the Medina River in Southwest Bexar County.
